If the fiber jumper is labeled with 1 or 2 :
1. Connect 1 s to UPLINK ports on the Main Hub.
2. Connect 2 s to DOWNLINK ports on the Main Hub.
3. Record which cable number and port number you connected to UPLINK and
DOWNLINK .
This information is needed when connecting the other end of the fiber cable to the
Expansion Hub’s fiber ports.
The fiber port LEDs should be off, indicating that the Expansion Hub(s) are not
connected.
If the fiber jumper is color-coded (for example, “blue” or “red”):
1. Connect “blue” to UPLINK ports on the Main Hub.
2. Connect “red” to DOWNLINK ports on the Main Hub.
3. Record which color and port number you connected to UPLINK and DOWNLINK .
This information is needed when connecting the other end of the fiber cable to the
Expansion Hub’s fiber ports.
